11. On Bit-Wise Decoders for Coded Modulation
Abstract : Coded modulation is a technique that emerged as a response to the growing demand for high data rates. It was devised to achieve high spectral efficiency with high reliability, potentially approaching Shannon’s capacity. The main idea of coded modulation consists in combining error-correcting coding with higher-order modulation. READ MORE

13. Spectral Mammography with X-Ray Optics and a Photon-Counting Detector
Abstract : Early detection is vital to successfully treating breast cancer, and mammography screening is the most efficient and wide-spread method to reach this goal. Imaging low-contrast targets, while minimizing the radiation exposure to a large population is, however, a major challenge. READ MORE

15. Optical frequency modulated continuous wave (FMCW) range and velocity measurements
Abstract : By using a tunable laser diode and fiber components small compact ranging and radial velocity measuring systems can be realized utilizing a frequency modulating continuous wave (FMCW) technique. The thesis start with an introduction that explains some basic theory behind laser diodes, photodiodes and different optical measuring techniques. READ MORE
